Definitions

  • This invention relates to an electronic component series wherein electronic components of the so-called parallel lead type having a plurality of parallel extending lead wires are regularly arranged and held.
  • Electronic component series are mainly used to feed electronic components to an automatic inserting machine which automatically inserts electronic components into printed circuit boards.
  • This invention relates to such an electronic component series for electronic components of the parallel lead type, but, as will be later described, it can be advantageously utilized in the process of production of electronic components of the parallel lead type.
  • an electronic component series generally includes a carrier band and electronic components held by the carrier band, the electronic components being held and regularly arranged on the carrier band by retainer means such as an adhesive tape.
  • An electronic component of the parallel lead type comprises an electronic component element and lead wires and such components are produced in the same manner as that for electronic component series in some cases. In other cases, they are produced in a different manner. That is, a plurality of lead wires are arranged side by side on a carrier band and then electronic component elements are fixed thereto as by solder dip, whereby electronic components are produced in large quantities at a time. The electronic components thus produced are removed from the carrier bands used for production and are then held on carrier bands for electronic component series and shipped.
  • FIG. 1 is a fragmentary plan view showing a portion of a conventional electronic component series as described above.
  • a plurality of electronic components 3 (in FIG. 1, only one is shown) are arranged on and distributed longitudinally of a carrier band 2 made, e.g., of thick paper.
  • Each electronic component 3 comprises an electronic component element 4, and lead wires 5, 6 parallelly led out of the electronic component element 4.
  • An adhesive tape 7 is applied to the carrier band 2 in a region closer to the end edge 2b of the carrier band. This adhesive tape 7 fixes the electronic components 3 in such an attitude that they can be accurately positioned for insertion into an automatic inserting machine.
  • Holes 8 are formed in the carrier band 2 between the adhesive tape 7 and the end edge 2a of the carrier band opposite to the side associated with the electronic component elements 4.
  • the holes 8 engage a sprocket (not shown) for feeding the electronic component series shown in FIG. 1 in the direction of its length and are formed to ensure that the components 4 are accurately positioned onto printed circuit boards in the automatic inserting machine.
  • a sprocket (not shown) for feeding the electronic component series shown in FIG. 1 in the direction of its length and are formed to ensure that the components 4 are accurately positioned onto printed circuit boards in the automatic inserting machine.
  • the positioning and fixing of the electronic components 3 on the carrier band 2 is effected by the adhesive tape 7 which bonds and fixes the electronic components 3 to the carrier band 2 with portions of the lead wires 5 and 6 held therebetween. Therefore, only the portions of the lead wires 5 and 6 contacted by the adhesive tape 7 function to properly position the electronic components 3 on the band 2. As such, the extensions 5a and 6a of the lead wires 5 and 6 extending in the direction away from the electronic component elements 4 do not aid in the positioning of the electronic components 3.
  • a principal object of this invention is to provide an inexpensive electronic component series which eliminates the problems described above and which is capable of allowing easy measurements of characteristic and securing an attitude for accurate positioning.
  • an electronic component series comprising:
  • an elongated, flexible carrier band having a top and a bottom edge
  • an elongated adhesive tape having a transverse width which is less than the transverse width of said carrier band, said tape being bonded to said carrier band with said lead wires of said electronic components held therebetween in a region closer to said top edge of said carrier band than said bottom edge of said carrier band;
  • each of said wires having an end portion which terminates at a location substantially immediately adjacent that end of said adhesive tape which is closest to said bottom edge of said carrier band whereby said lead wires do not extend to the bottom edge of said carrier band, each said lead wire having a substantially constant width throughout its length, and each said lead wire having a burr formed at the end thereof which burr engages said carrier band.
  • this invention is an electronic component series including a flexible carrier band, a plurality of the parallel lead type electronic components arranged on and distributed longitudinally of said carrier band, and an adhesive tape bonded to the carrier band with the lead wires of the electronic components held therebetween in a region closer to the end edge of the carrier band associated with the electronic components, the electronic component series being characterized in that the lead wires are cut off adjacent the end edge of the adhesive tape associated with the extremities of the lead wires and thus the extremities of the lead wires are removed.
  • the lead wires may be cut off by being punched round together with a carrier band. Also, the lead wires may be cut off by being punched together with a carrier band so that the carrier band may have slits.
  • holes for moving the electronic component series are formed in the carrier band. These holes may be formed in the middle of the width of the carrier band, or may be formed in the region closer to the direction of the width of the carrier band.
  • the unnecessary lead wire extensions can be recovered, so that the cost of the electronic component series can be effectively reduced. Further, the absence of the unnecessary extensions of the lead wires precludes trouble in moving the carrier band and the possibility of the attitude of the electronic components being upset and of the adhesive tape being peeled as otherwise might be caused by pending or entanglement of the extensions. Similarly, since burrs engaging with the carrier band are formed in the severed portions of the lead wire as a result of the cutting-off of the lead wires, the electronic components are retained more positively thus making it possible to prevent upsetting of the attitude of the electronic components more effectively.
  • the cutting-off of the lead wires is effected subsequently to the measurement of the electronic components or to taping, the production is easier, and moreover shipment can be secured after the characteristics of the electronic components have been confirmed.

  • an electronic component series 11 comprises, roughly, a carrier band 12, electronic components 13, and an adhesive tape 17.
  • electronic components 13 are distributed longitudinally of a long-sized, carrier band 12 made, e.g., of thick paper, synthetic resin or metal and arranged thereon in the proper attitude for positioning in an automatic inserting machine.
  • the electronic components 13 are of the parallel lead type, having lead wires 15 and 16 parallelly extending therefrom.
  • An adhesive tape 17 is bonded to the carrier band 12 with the lead wires 15 and 16 held therebetween in a region closer to the side of the carrier band associated with the electronic component elements 14 than to the remaining side of the carrier band.
  • the electronic components 13 are held in the proper attitude by the adhesive tape 17.
  • Holes 18 are formed in the carrier band 12, arranged axially centrally thereof, said holes 18 being present for the purpose of engagement with a sprocket to feed the electronic component series 1 and for the purpose of accurate positioning in the automatic inserting machine.
  • the lead wires 15 and 16 are cut off adjacent the end edge 17a of the adhesive tape 17 associated with the extremities of the lead wires 15 and 16, and the extremities of the lead wires 15 an 16 are removed. That is, the electronic component series 11 in this embodiment is formed in such a manner that after the conventional electronic component series 1 shown in FIG. 1 has been completed, the lead wires are cut off adjacent the end edge of the adhesive tape associated with their extremities.
  • the portions to be cut off are extensions 15a and 16a shown in phantom lines in FIG. 2, and the cutting-off process is shown in FIG. 3. Initially the electronic component series 11 with the extensions 15a and 16a which have yet to be cut off are placed on a support block 19.
  • a cutting blade 20 is lowered in the direction of arrow X adjacent the end edge 17a of the adhesive tape 17 associated with the extremities of the lead wires 15 and 16, thereby cutting-off the lead wires 15 and 16, whereupon it is immediately retracted in the direction of arrow -X.
  • the lead wires 15 and 16 are severed in this severing process. Since the cutting blade 20 is retracted in the direction of arrow -X immediately after cutting-off the lead wires 15 and 16, the carrier band 12 is not subjected to any significant damage. Therefore, there is no danger whatsoever of the strength of the electronic component series 11 being decreased. As is clear from FIG.
  • the cutting-off of the lead wires 15 and 16 which is characteristic of this embodiment is easily achieved by performing the positioning of the cutting blade 20 alone, and since it does not require the complicated alignment of blades as in the case of cutting by upper and lower blades, it can be implemented with extreme ease.
  • FIG. 4 is a fragmentary plan view showing part of a second embodiment of this invention
  • FIG. 5 is a fragmentary cross-sectional view showing part of the process for producing the embodiment shown in FIG. 4.
  • the feature of the second embodiment lies in the fact that the cutting-off condition of the lead wires 15 and 16 differs from that in the first embodiment. The rest is the same as in the first embodiment, so that a description thereof will be omitted by giving the corresponding reference numerals to the corresponding parts.
  • the front ends of the lead wires 15 and 16 are cut off by being punched by a round punch together with the carrier band 12. Referring to FIG. 5, the punch 21 is disposed above the electronic component series 11 having unsevered lead wires 15 and 16 and placed on a support block 19.
  • the punch 21 is lowered in the direction of arrow X adjacent the end edge 17a of the adhesive tape 17 associated with the extremities of the lead wires, thereby punching the lead wires 15 and 16 together with the carrier band 12. Thereafter, it is retracted in the direction of arrow -X and the electronic component series 11 shown in FIG. 4 is thus produced.
  • the portions of the lead wires 15 and 16 punched by the formation of round holes 22 and 23 can be recovered as well as the extensions 15a and 16a which have been cut off and removed. Therefore, the cost of the electronic component series 11 can be reduced as in the first embodiment. Further, since the extensions 15a and 16a of the lead wires are absent, it goes without saying that the same effects as in the first embodiment can be achieved.
  • FIG. 6 is a fragmentary plan view showing part of a third embodiment of this invention, corresponding to FIGS. 2 and 4.
  • the feature of the third embodiment lies in the fact that the lead wires 15 and 16 are cut off so that slits 24 and 25 may be formed. That is, in the third embodiment, the cutting blade 20 shown in FIG. 3 not only cut off the lead wires 15 and 16 but also pierces through the carrier band 12, whereby it not only cuts off the lead wires 15 and 16 but also forms the slits 24 and 25 in the carrier band 12. Therefore, as in the second embodiment, the third embodiment has the advantage that there is no need for accurate adjustment of the retraction point for the reciprocating movement of the cutting blade 20. The rest is the same as in the first embodiment, so that a description thereof will be omitted by giving the corresponding reference numerals to the corresponding parts.
  • FIG. 7 is a fragmentary plan view showing a fourth embodiment of this invention.
  • the feature of the fouth embodiment lies in the fact that the holes 18 are formed not in the middle of the width of the carrier band 12 but in a region closer to the end edge 12a of the carrier opposite to the electronic component elements 14. The rest is the same as in the first embodiment, so that a description thereof will be omitted by giving the corresponding reference numerals to the corresponding parts. Since the holes 18 are disposed closer to the end edge 12a, it is possible to narrow the width of the carrier band 12, as is clear from FIG. 7. That is, an electronic component series 11 can be formed by using a narrower carrier band 12 provided that it fits to the feed mechanism of the automatic inserting machine.
  • extensions 15a and 16a of the lead wires 15 and 16 may be present on the plane of the carrier band 12 in the form of free ends or with their ends connected together.
  • the holes 18 need not necessarily be formed such that they are spaced from the adhesive tape 17, and thus the holes, not shown, may be formed in the carrier band 12 and the adhesive tape 17 at a time.
